I like FriendFeed. It's simple and useful, and it brings the utilitarian-but-well-engineered feel of Gmail to social media (several prominent Google/Gmail alums developed FriendFeed).
FriendFeed has one great and, I think, unique feature called "Create an imaginary friend." It lets you track people from other social media sites who haven't yet signed up for FriendFeed.
This is a smart and useful way of dealing with problems like cold-start and social network migration. Your friends don't need to move to FriendFeed for you to get value from it (and them).
But--honestly--the real reason I'm writing this post is because this button just makes he happy. It's an unexpected reminder of a time when I didn't need to keep track of the people I knew, when my relationships weren't a measure of my value, and when I used to hang out with Evel Knievel all day long, jumping Snake Canyon.
But I know all of this will be spoiled once I click the button. So I don't.
